Zebrafisken er ideel til at studere regenerering af voksne organer, herunder den voksne mesonephric nyre 6. Nylige undersøgelser har benyttet sig af molekylære markører og nye transgene reporter linjer til bedre karakterisere de trin, der opstår under nephron regenerering og hvilke celler kan være ansvarlig 7,12. Observation af urin afstøbninger har været anvendt i over et århundrede at diagnosticere nyresygdom hos mennesker 16. Her bruger vi tilstedeværelsen af ​​afstøbnin...

Nyren er afgørende for fluid homeostase, blodtryk regulering og filtrering af affald fra kroppen. Selvom pattedyr er i stand til at reparere eksisterende nefroner efter skade ved brug differentierede epitelceller 1-4, synes de at mangle en pulje af reserverede stamceller 5 og er ude af stand til at danne nye nefroner de novo. I modsætning til pattedyr, voksne fisk er i stand til at danne nye nefroner hele voksenlivet at understøtte væksten af fisk og som respons på skade 6,7. Zebrafisken, Danio rerio, er en uvurderlig model organisme for studiet af orgel regenerering 8-10 og har potentiale til at levere stærke indsigt i ansøgninger om engineering reparation af menneskelige nyrer. Tg (Lhx1a: EGFP) transgen 11 er blevet vist at mærke en pulje af nephron progenitor celler i den voksne zebrafisk nyre 12 imidlertid mekanismer, der styrer respons lhx1a + -celler af skader rEmain uklar. Aminoglycosidet gentamicin er et meget anvendt antibiotikum med kendte nefrotoksiske og ototoksiske virkninger hos mennesker 13. Intraperitoneal injektion af gentamicin er en etableret metode til at inducere akut nyreskade i fisk 6. Denne skade i fisk efterligner tabet af rørformede epitel og ardannelse i glomeruli, der forekommer hos mennesker efter gentamicin overdosis 14. Inducerende skade i zebrafisk af gentamicin injektion er en bekvem måde til at inducere en stærk, synkron regenerering respons, med mange nye nefroner produceret og samtidig behandling via stadier af dannelse, proliferation og differentiering. Denne protokol beskriver vores metode for robust og reproducerbar skade i den voksne zebrafisk nyre ved at udnytte en noninvasiv visuel screening proces for at minimere outliers. Vi drage fordel af det faktum, at skaden med gentamicin fører til døden af ​​epitelial nyrevæv og formation af renale tubulære afstøbninger, som derefter ophobes i masserne i mesonephric kanaler og kloak. Disse er bestået af fisk og kan observeres visuelt i vandet. Dette giver os mulighed for at screene for fisk med en stærk ikke-letal skade, som derefter kan samles til yderligere eksperimenter. Minimering af antallet af skadede fisk eller fisk, der dør, før de når endepunktet af forsøget fører til en mere ensartet og effektiv dataindsamling og analyse. Desuden er ingen specielle anordninger eller reagenser påkrævet, hvilket gør denne fremgangsmåde omkostningseffektiv og egnet til anvendelse i en akademisk eller undervisning indstilling. Ved hjælp af vores metode, her viser vi de stigende virkninger af gentamicin dosis på nyre regeneration samt effekten af ​​øget temperatur.

kidney regeneration in adult zebrafish by gentamicin induced injury

The kidney is essential for fluid homeostasis, blood pressure regulation and filtration of waste from the body. The fundamental unit of kidney function is the nephron. Mammals are able to repair existing nephrons after injury, but lose the ability to form new nephrons soon after birth. In contrast to mammals, adult fish produce new nephrons (neonephrogenesis) throughout their lives in response to growth requirements or injury. Recently, lhx1a has been shown to mark nephron progenitor cells in the adult zebrafish kidney, however mechanisms controlling the formation of new nephrons after injury remain unknown. Here we show our method for robust and reproducible injury in the adult zebrafish kidney by intraperitoneal (i.p.) injection of gentamicin, which uses a noninvasive visual screening process to select for fish with strong but nonlethal injury. Using this method, we can determine optimal gentamicin dosages for injury and go on to demonstrate the effect of higher temperatures on kidney regeneration in zebrafish.

Gentamicin skade kan bekræftes visuelt ved observation af renale epiteliale afstøbninger i vand (figur 1). Forskellige doseringer af gentamicin blev anvendt til at skade voksen vildtype TuAB zebrafisk, hvilket resulterer i et stigende antal lhx1a + cellulære aggregater i regenererende nyre (figur 1A - D). Hvide afstøbninger kan let ses i vandet 1 dag efter skade (Figur 1E - H). En lav dosis af gentamicin resulterede i de fl...
